METAL BUILDING FRAME on sAsH.

Specication of Letters Patent.

Patented Ang; 1, i911.

Application filed September 24, 1910. Serial No. 583,584.

a citizen of the United States, and a resident ofr New Castle, county of Lawrence,

and State of Pennsylvania, have invented certain new and useful Improvements in Metal Building Frames or Sash, of which the following is a specification.

This invent-ion relates to building frames.-

or sash constructedl of angle bars (preferably of 'l' section) in which the bars are jointed. together by interlocking. them in a manner to give them rigidity and strength as described in my previous applicatlon filed Novemberv17 1 `909. Serial No. 528,501.

One ob'ect of the present invention is to increase the strength of the structure and at the same time' to provide a firmer joint between the parts, to which end the members are composed of a relatively thick base, relatively thinner flanges extending from opposite sides of the base, land al web extending perpendicularly to the base, preferably along the middle line thereof; the parts being interlocked as ,in my previous application referred to but in a manner to bring the thickbases into abutment so that not only is the bar strengthened but its connection is improved.

A further object is to provide means for securing in place the closure plates (glass, tiles, slates, or the like) which are to be fitted in the openings of the frameor sash,-

to which end I provide .a cap which is fitted to the web of the angle iron and extending down the side thereto with a rentrant bend entering between the web and the edge of the plate so as 'to confine the plate edge wise and with a flange overlying theplate so as to hold the plate downupon the ange of the frame;4 the plate being preferably embedded in aplastic packing such as nutty, cement yor the like and the cap being preferably provided with a fibrous packin' through lwhich it bears upon the plate; an

.the cap being preferably made double so as to fit over the web and enter into coniining. relation to the two plates on opposite sides of the web. For some classes of wor-k I provide'a cam 'shaped dog or latch lpivotedly connected with the web and adapted to be brought into' bearing 'up'onthe plate by swinging it. upon its axis; this dog or latch being preferably fitted in an opening in the web'and having a lip that enters bei tween the web andthe plate to prevent the pli'cation referred to.

dog from leaving its bearing in the web and also spacing the plate from the web; the bearing flange or edge of the latch being rendered somewhat resilient so that it euters into cushioned bearing upon the plate.

A further feature consists in the method of assembling the parts which are inter locked in accordance with my previout` ap- 'The invention will be fully `understood on reference to the accompanying drawings in whichj `Figure 1 is a front view of a frame or sash embodying. some of the features of the present invention. Fig. 2 is a section on the line 2--v2, Fig. l. Fig. 3 is a transverse section, and Fig. 4 a plan View of the interlock formed between' a continuing and two abutting members. Figs. 5 and 6 are detail views showing two different sections of metal that may be used incarrying out' some features of the invention. Fig. 7 is a sectional view illustrating the method of the vertical'bars of a frame or sash con-v structed in accordance with my previously filed application and involving the novel features of construction referred to in the present case. sash are united by iangednterlocksband web-interlocks 7, as described in my previous The members of this frame or application, but each member not only comprises the web 8 and the lateral flanges' such as heretofore employed' by me, but has a relatively vthickbase 10 from which the 'web and 4flanges project. This base -not only serves the purpose of` affording greater rigidity to the bar or rail or in other words permits the use of anges 9 which are relatively ,thin, but it involves a special advantage in that it alfords increased abutment-bearing between the side of the base on 'one member and the vend of the base on another member. Whereas the thin flanges are such that the tongues lla as heretofore employed may be more readily deiected frori'the plane of the flanges so that they will not break when the parts are repared for assemblin and the tongues t ereater v bent to bring t em .into the same plane.

loo

in this manner I have devised the method of,

deflecting the engaging tongues on the {lang-es in opposite d1rections so that after the -parts are brought into abutment the tongues may be pressed into the same plane to lirmly interlock the parts as suggested in F ig. 7.

I claim 1. In a metal building-frame `or sash, frame-members, each constructed with a base, baseelianges, and a web and united by a joint comprising abutment between the bases and between the webs, and interlocks,

'between the base lianges; theinterlocking A portions of said base anges being of less thickness than the bases,

2. In a metal building-frame or sash, frame-members, each constructed with a base,v base-ilanges7 and a web and united by a joint comprising abutment between the bases and between the webs, and interlocks between the base flanges; the interlocking portions of said base flanges being of less thickness than the bases, the bases being thicker than the lianges, whereby the abutting bases exten beyond the planeet said interlock.

3. In a metal buildingframe or sash, frame-members, each comprising a relatively thick base, relatively thinner flanges, and web perpendicular to the base, the iiangeof oneof said members being provided with a lateral recess that receives the base of themother member and with undercuts extending from said recess longitudi nally of said iiange; and said other member having the end of its'thick base in abutment with the side of the thick base of the recessed member and having laterally extend.- ing tongues .on its'flanges entering the longiceases .tudinalundercuts in the first named member.

4. InA a metal buildingi'rame or sash,

frame-members, nach comprising arelatively from said recess 'longitudinally of said flange; and said other member having the end of its thick base in 'abutment with the side of the thick base of the recessed member and having laterally extending tongues 'on its flanges entering the longitudinal un: dercuts in the'irst named member; said members -also having their webs in abutment.

5.- In a metal buildingeframe or sash, frame-members each comprising a relatively thick base, relatively thinner flanges, and a web perpendicularv to the base; the flanges of one of said members being. provided with a lateral recess that receives the base of the other member and with undercuts extending from said recess. longitudinally of said flange; and said other member having the end of its thick base in abutment with the side of the thick base of the recessed vmembers and having laterally extending tongues on its flanges, and said webs being constructed with an interlocking opening and projection. i

6. In a frame 'or sash, frame-members having thick bases relatively thinner flanges and perpendicular webs? connected by joints consisting of-abutments between the base and webs also laterally and longitudinally sustaining dowel and slot interlocks between the webs, and interlocks between the flanges. y
